The research of PCD cutter in industrialized countries has been developed earlier, and its application is more mature. Since the first synthetic diamond in Sweden 1953, the research on the cutting performance of PCD cutter has gained a great deal of results, and the application range of PCD cutter and the dosage are enlarged rapidly. At present, the internationally renowned synthetic diamond composite film producers are mainly British DeBeers companies, GE Companies, Sumitomo Electric Co., Ltd. Japan. In the first quarter of 1995, the production of PCD cutters in Japan was reported to be 107,000%. The application range of PCD cutter has been extended from the initial turning machining to drilling and milling. A survey of Superhard cutters conducted by a Japanese organization shows that the main considerations for people choosing PCD cutters are based on the advantages of surface precision, dimensional precision and tool life of PCD cutter. The synthetic technology of diamond composite Slice has been developed greatly, DeBeers company has introduced polycrystalline Diamond Composite film with 74mm diameter and thick 0.3mm.

The domestic PCD cutter market with the development of tool technology has been expanding. At present, China's first automobile group has more than more than 100 PCD knife use point, many man-made board enterprises also use PCD cutter for wooden products processing. The application of PCD Cutter has further promoted the research of its design and manufacturing technology. At home, Tsinghua University, Dalian Polytechnic University, Huazhong Polytechnic University, Jilin University of Technology, Harbin Institute of Technology are actively conducting this research. PCD Tools engaged in R &amp; D, production of Shanghai Schuberhardt, Changzhou Merck Tool Zhengzhou New Asia, Nanjing Blue Flag, Shenzhen run Cheung, Chengdu Tools Research Institute, Chengdu Dai Mengdi and other dozens of units. At present, the processing range of PCD cutter has expanded from traditional metal cutting processing to stone processing, timber processing, metal matrix composites, glass, engineering ceramics and other materials processing. Through the analysis of the application of PCD tools in recent years, the PCD cutter is mainly used in the following two aspects: ① processing of refractory nonferrous metals materials: Machining difficult non-ferrous metal materials with ordinary cutter, often produces the tool easy to wear and low processing efficiency defects, while PCD cutter can show good processing performance. If using PCD cutter can effectively process the new engine piston material-hypereutectic silicon aluminum alloy (the research on the processing mechanism of the material has been breakthrough). ② difficult processing non-metallic materials: PCD tools are very suitable for stone, hard carbon, carbon fiber reinforced plastics (CFRP), wood-based panels, such as refractory non-metallic materials processing. such as Huazhong University of Science and Technology 1990 years to achieve the use of PCD cutter processing glass; the application of laminate flooring and other wood-based plates (such as MDF) is becoming more and more widespread, and it can effectively avoid the defects of cutting tools with PCD cutters.
